[Gems-users] Generated files in ruby

["Lei Yang" <lya755@xxxxxxxxxxxxxxxxxxxx>]

Dear list,

 

In gems/ruby/generated, there are a lot of generated C and h files for a certain protocol, say MOSI_SMP_bcast. I wonder how these files are generated and what are the source files. For example, in L1Cache_Entry.C, class 'L1Cache_Entry' inherits from 'AbstractCacheEntry', which is in turn, defined in ruby/slicc_interface/AbstractCacheEntry.h . However, as I understand the MOSI_SMP_bcast protocol, in addition to L1I, L1D cache, each processor also owns a unified L2 cache. But there is no L2Cache_Entry.C/h file in ruby/generated. Since I want to do some modification to the L2 cache architecture, I need to modify the L2Cache_Entry class, if presents. More importantly I want to understand how these files are automatically generated, because in MOSI_SMP_bcast-cache.sm I can only see these lines related to L1Cache_Entry and L2Cache_Entry:

 

CacheMemory L1IcacheMemory, template_hack="<L1Cache_Entry>", constructor_hack='L1_CACHE_NUM_SETS_BITS,L1_CACHE_ASSOC,MachineType_L1Cache,int_to_string(i)+"_L1I"', abstract_chip_ptr="true";
  CacheMemory L1DcacheMemory, template_hack="<L1Cache_Entry>", constructor_hack='L1_CACHE_NUM_SETS_BITS,L1_CACHE_ASSOC,MachineType_L1Cache,int_to_string(i)+"_L1D"', abstract_chip_ptr="true";
  CacheMemory L2cacheMemory,  template_hack="<L1Cache_Entry>", constructor_hack='L2_CACHE_NUM_SETS_BITS,L2_CACHE_ASSOC,MachineType_L1Cache,int_to_string(i)+"_L2"', abstract_chip_ptr="true";

 

Your help will be greatly appreciated!!

 

Thanks,
